TOOL-HOLDER.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed June 20, 1914. Serial No. 846,315.

To all whom it may concern:

Be it known that I, GEORGE H. MASON, a citizen of the United States, residing at Lubec, in the county of Vashington and State of Maine, have invented certain new and useful Improvements in Tool-Holders,

of which the following is a specification.

This invention has for its object to provide a tool holder of improved construction embodying a tool-receiving head adjustably secured to a body member, the latter having means for automatically securing the adjusted head in adjusted position when the tool holder is operatively positioned.

Another object is the provision of means for reliably securing the tool in the head simultaneously with the securing of said head to the body member.

With these and other objects in view, the invention consists of the novel construction, arrangement and formation of parts, as will be. hereinafter specifically described, claimed and illustrated in the accompanying drawings. in which:

Figure 1 represents a perspective view of the tool holder. Fig. 2 represents a bottom plan view thereof. Fig. 3 represents a longitudinal sectional view through the holder. Fig. 4 represents a longitudinal sectional view taken at right angles to Fig. 3. Figs. 5 and 6 represent top plan views. partly broken away, of the tool, showing the several adiustments relative to the body member. Fig. 7 represents a transverse sectional view on the line 77 of Fig. 3. Fig. 8 represents a perspective view of the tool locking member, and Fig. 9 represents a perspective view of the head removed.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 10 indicates the body of the tool holder having a recess 11 extending outwardly a distance from the lower face and communicating with a longitudinal opening 12. lhe front wall 13 of the recess 11 is inclined and the front end of the body 10 is slightly enlarged and concaved. as indicated at 14:. A head 15 of hollow formation and having rearwardly extending apertured ears 16 is positioned within the concavity 1 1 of the body 10 and receives the tool 17.

A tool-engaging and securing member designated generally by the numeral 18 is positioned within the hollow head 15 and is provided in its front edge with a groove or channel 19 partially receiving the tool 17. The member 18 is provided with a pair of spaced rearwardly extending cars 20 having apertures 21 therein registering with the apertures in the cars 16 of the head 15.

A block 22 is positioned within the recess 11 of the body 10 and provided with a beveled front end abutting the inclined front wall 13 of the recess. A longitudinal opening 23 is formed through the block 22 and rotatably receives a bolt 24 having its front end enlarged, positioned between the ears 20 of the tool engaging member 18 and having an aperture registering with the aperture 21 in said member 18. The lower end of the bolt 24 is provided with a plurality of screwthreads on which is fitted a nut 25 nonrotatably seated in an enlargement of the longitudinal opening 23 in the block 22. A. seat 26 is formed in the rear face of the member 18 between the ears 20 and receives a spring 27 engaged at its opposite end against the enlarged end 24 of the bolt 25L. A pivot pin 28 is positioned through the apertures in the ears 16, 20 and the aperture in the enlarged head 24c of the bolt 24 and pivotally secures the head 15 to the body member 10 of the tool holder.

Ihe opening 12 in the body 10 is slightly larger than the bolt 24; and permits the block 22 to move a distance outwardly. Outward movement of the block 22 against the in clined face 13 of the recess 11 moves the bolt 24 a short distance forwardly, permitting pivotal adjustment of the head 15 and adjustment of the tool 17. \Vhen the body 10 is operatively positioned on the bed of the machine and secured by a suitable screw engaged against the top face thereof. the block 22 is forced inwardly and, working against the inclined face 13 of the recess, is moved a distance rearwardly drawing on the bolt 24, thus insuring a firm frictional 1 engagement of the head 16 in the concaved end 14 of the body. The securing member 18 engaged between the concaved end 14 of the body and the tool 17 respectively lock the latter in adjusted position when the tool holder is operatively positioned on the bed of a machine.

lVhat I claim is:

1. A tool holder comprising a body, a head pivotally secured to said body, a tool adjustable in said head, said body having a recess therein provided at its forward end with an inclined Wall, and means for simultaneously securing said head and said tool in adjusted position including a block movable against said inclined Wall.

2. A tool holder comprising a body having a recess formed longitudinally therein provided With an inclined front Wall, a head, a block positioned in said recess having a beveled end engaging said inclined Wall, a bolt adjustably secured in said block having an apertured forward end, and a pin pivotally securing said head to said bolt.

3. A tool holder including a body having a recess provided With an inclined front Wall, a block positioned in said recess having a beveled end engaging said inclined Wall, a bolt adjustably secured in said slot and having an apertured forward end, a head, a tool adjustable in said head, a pin pivotally securing said head to the apertured end of said bolt, and means intermediate said tool and the forward end of said body for vsecuring Said tool in adjusted position.

4. A tool holder comprising a body, a head, a tool adjustable in said head, and means for simultaneously securing said head and tool in adjusted position including an eye bolt adjustably secured in said body and carrying a pin pivotally supporting said head.

5. A. tool holder comprising a body having a longitudinal recess therein, a head, a tool adjustably positioned in said head, and means for simultaneously securing said head and tool in adjusted position including a block movable longitudinally in said recess Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents Washington, D.
